Flower-Visiting Insects
of Plantain-Leaved
Pussytoes
Antennaria plantaginifolia (Plantain-Leaved Pussytoes)
(on staminate flowers, Halictid bees suck nectar or collect pollen, while beetles feed on pollen, as indicated below; other insects suck only nectar on staminate flowers; on pistillate flowers, all insects suck nectar; insect activity is unspecified when the flower gender is unknown; depending on the authority, this plant is either insect- or wind-pollinated; Antennaria parlinii & Antennaria fallax of some authors can be considered varieties of Plantain-Leaved Pussytoes; most observations are from Robertson, otherwise they are from Moure & Hurd, Evans, and MacRae as indicated below)
